Used as a reactive monomer in the synthesis of fluorinated polymers, offering enhanced thermal stability, chemical resistance, and low surface energy. Commonly applied in specialty coatings and thin films where water and oil repellency are required. Its styrenic structure allows for free-radical polymerization, enabling copolymerization with other vinyl monomers to tailor material properties. Frequently utilized in surface modification to improve non-stick performance and in the development of hydrophobic materials for electronic or optical applications.
